Parallel running 10-0 and 11-0 nylon sutures were used in 76 consecutive penetrating keratoplasties on patients with keratoconus. Removal of the 10-0 suture at eight to 12 weeks allowed for early visual rehabilitation postoperatively. The use of various trephine sizes and the use of a bridle suture versus a scleral ring were evaluated by several visual parameters. The incidence of complications with the double running suture was not greater than that obtained with other suture techniques.
